MAX BEC 2 is designed to power the receiver and servos in the model. MAX BEC 2 is a linear voltage stabilizer with an adjustable output voltage. The output voltage is set using a jumper and in one of four positions: 5.0V, 5.4V, 5.7V or 6.0V. MAX BEC 2 can be powered using NiXX and Li–XX cells. MAX BEC also gives an indication of used capacity of the battery with four LED´s.
An integral part of the MAX BEC 2 is an electronic switch that uses a highly efficient type of MOSFET transistor. The main benefits of the MAX BEC 2 include a high voltage rating (to 12 cells NiXX) and low current in the off state (170 μA). The analog voltage stabilization does not contribute to radio interference.
